Coming off of my pool pump is a valve with hose attachment (similar to what you would have on your house almost to have a hose hooked up). I noticed the old home owner has a hose laying out here as well. I was never explained what this was for so I haven't touched it and anytime I have needed to drain the pool I have just used my sump pump directly in the pool.
Is this valve and hose attachment meant to drain the pool when needed for whatever reason (excessive rain for example)? Is it as simple as hooking up the house and turning the valve on while the pump is running? I didn't want to touch it until asking here first. Picture of what I am describing can be found here
